well I am not really as concerned with the prize myself but I like to understand the rules when entering a contest.

It looks like the older caption contests has a similar format to keep things simple. Looking through some of them, it doesn't look like a problem. Maybe if it does, I think that coordinator will change it around. Seeing that it hasn't those couple of weeks, let's go with the arbitrariness that has been presented.

Just to note, the only rules that I can see actually being enforced here are the standard crunchyroll rules, the ones usually regulating spam and inappropriate posts. Aside for those, again, let's go with the arbitrariness that has been presented. "LAWL"
